Is spaceship armor useless?

And it can't have PD, because then it has less armour, and with less armour it will be shredded by PD.

Good point defense (against non-armored standard missiles) will use "smaller systems" and have SM+7 tertiary missile batteries. Its only like 1d-2 damage at that point. Two layers of nanocomposite is enough. Also it only needs to be on the front side, unless you stick point defense drones out in front of the main ship.
